Yeah, I know cycle as well as many other products are bullcrap. But I have been unable to find bio spira in any pet shops, and the closest thing I can find is something called TurboStart by fritz-zyme. Probably another bs thing, but it does have to be refrigerated and it is specifically for either fresh or salt water. Sounds a little more plausible than a lot of the other cycle 'boosters". Does anyone have any experience with this product? I've heard all the skepticisms so please don't post unless you've used it, I'm having a bit of a blind hope that maybe someone has used it and it has worked.
